OPERATION
• Take the monocular out of the case.
• Install the battery into the housing with the polarity order as shown on the scope. Battery
Type: 3 Volt Lithium, #CR123A .When installing the battery one should keep in mind that the
polarity of the battery should coincide with the diagram on the body next to the battery hous-
ing cap.
• Slide the switch to turn the unit on with the protective lens cover still attached to the lens.
Do
not turn the unit on in the daytime without the protective lens cap on.
You should see
green glow in the eyepiece.
• Observe the scene and adjust the diopter for optimal image clarity.
• You may now enter a dark environment or simply shut the lights off in order to darken the
room.
• Next, remove the lens cap/daylight filter. Adjust the front lens for the distance of the focus.
You should not have to readjust the diopter.
FOCUSING
To focus the NightStar, first you will need to adjust the diopter. Simply turn
the diopter clockwise until it stops. Then, while looking throught the diopter
at an object, slowly turn the diopter back counter clockwise until the grain
in the image is sharp.
NOTE:
We suggest that you focus the diopter during daylight with the
filter on.
Next focus the front lens until the image and the grain are both sharp. When
you are in low-light conditions and the daylight filter is off, you may focus
the front lens to receive sharp image, the diopter should not be adjusted.
NOTE:
The front lens should be readjusted as you view objects at different
distances.
INFRA-RED ILLUMINATOR
Infra-red illuminators, or IR illuminators, are common to night vision. The
IR light greatly enhances the performance of the NightStar while remaining
almost totally invisible to the naked eye. The IR illuminator on the NightStar
is located underneath the front lens, next to the battery compartment.
The IR illuminator is powered up by sliding the switch to position labeled
“IR”. It is important to remember that the IR illuminator is simply an infra
red light source, and like any light source, it may loose its effectiveness
over a great distance.
STORAGE AND CARE
• If the device is not to be used for extended period of time (more than 10 days) remove the
battery.
• Avoid touching lenses. If fingerprints or traces of dirt or dust appear, clean their surface with
a Photographic lens cleaning tissue.
• Keep lens cap/daylight filter on when not in use.
• The MO-3 is not harmful to the user or the environment.
• Do not disassemble except to clean the front lens and eyepiece:
it will void your warranty.
